SINGER Heavy Duty 4423 Sewing Machine Review

Editor’s Pros and Cons


The SINGER Heavy Duty 4423 Sewing machine is very versatile.  We love that it can sew many different types of fabric.  There have been reports of this machine sewing upholstery vinyl, although we have yet to test that one. However, we have successfully sewed patches onto a jacket.  We were amazed at how well we sewed the rip in a pair of corduroy pants we had to lay around.  Other materials we have tested have included hemming denim jeans, sewing dresses out of cotton materials for toddlers, and sewing a silk pillow.  It has been reported that this machine can sew through several pieces of denim at once.  We have yet to test this, so we can not confirm it yet, but we are hopeful that it will be strong enough to do so.

When you are sewing with the SINGER machine, a tip I can offer is to be certain that you pick a needle that goes with the thickness of your material.  After all, you would not pick a thin needle for super thick material, as the needle will most likely break off.  It is always a good idea to have extra needles on hand as well.

Part of the reason this machine is so versatile is that it comes with so many stitching options.  Twenty-three is a great number, and if you are just starting, it is not too much to overwhelm you, but still enough to offer a great choice.  The choices that you have for stitches on this machine include the following:

  • 12 decorative
  • 6 basics
  • 1 buttonhole
  • 4 stretch

With the turn of the dial, we found you can easily adjust the stitches.  The stitch width dial has settings from zero to six, and the stitch length dial has four settings that start at 0.5 up to 4mm. When you adjust the length, we have found that you can create different effects.

The sewing machine is also very fast.  We have found that you can easily do 1,100 stitches per minute if you are a professional stitcher.

Many Modern Features

One of the biggest things we first noticed about the SINGER Heavy Duty 4423 Sewing Machine was all the modern features.  This goes without saying that we like the devices we purchase beefed up in order to get our money’s worth.  And so far, we feel like, in the feature department, they completed this task beautifully.  Here are some of the modern features you will be sure to notice:

  • Automatic needle threader (No aggravation or straining of the eyes)
  • A top-drop-in bobbin (Simple to insert/remove, can tell if the thread is getting low as the cover is transparent)
  • Stainless Steel BedPlate (ensures any and all material will glide right through the machine)
  • 3 Needle positions (For the stitching specialty)
  • A foot control pedal (Adjustable to regulate how fast or slow you sew)
  • Snap-On presser feet (It enables one to adjust the presser foot instantly)
  • Adjustable presser foot pressure control (Line up the pressure with the material)
  • Extra-high presser foot lifter (Better clearance when working with heavier materials)
  • Onboard storage (Easy entrance to pieces stashed in the detachable sewing container)
  • Free arm (Effortless entrance to cuffs, hems, collars and other unreachable spots)
  • Automatic reverse (Simple way to reinforce the stitches)
  • Adjustable stitch length and width (a very important feature for a sewing machine to have)
  • Super Powerful Motor (At 105W, this motor is sure to stitch through tough materials like denim and upholstery. It is even possible for this machine to sew through several layers at once)

Foot Control Pedal

If you have never used a foot control pedal on a sewing machine, it will take some time to get used to it.  But this is to be expected.  You can easily practice with a scrap piece of material to learn what the best speed is for you on the foot pedal. Many users, as well as us, have found that practice in this area will make perfect.

We have found that if you place your entire foot on the pedal it is easier to run.  Just placing the tip of your toes on the pedal may cause your foot to slip, which may mess your stitch-up.

We have found that the foot control pedal is flexible to use.  We like to raise the foot to manage thicker pieces of material.  We have also found that if you are just starting to sew, you can leave the foot pedal where it is set at, as it comes pre-set.  This allows you one less thing to do when setting up the machine.

Now, if you desire to, you can adjust the thread at this point.  This will make sure you have a high-quality stitch on your fabric.  You only have to worry about the upper thread as the lower thread tension will be set by the manufacturer.

With the SINGER Heavy Duty 4423 machine, you have four feet of choices.  These include:

  • All-purpose foot – used for the majority of your sewing projects.
  • Buttonhole foot – used for adding buttonholes, slots for ribbon and more.
  • Zipper foot – used for adding zippers, piping, cording and more.
  • Button Sewing Foot – used for adding buttons.

There are also nine other feet that you can purchase:  Hemmer, satin stitch, overcasting, blind hem, cording, straight stitch/quilting, gathering, even feed, and darning/embroidery. With these feet choices, we have found that a wide variety of options have opened up the possibilities.  We love how easy it is to change the feet out.  Simply snap off and then back on.


One of the greatest things about a sewing machine is how portable it is.  If you love to sew as much as we do, then you know that having a sewing machine that does not weigh as much as a 100-pound sack of potatoes means a lot!  The SINGER 4423 is very portable.  At less than 15 pounds, you can easily move it out of one room into another to sew.  Or if you do alterations as a side job, you can afford to go to someone’s home if they are not able to travel to you.

We also appreciated the dust cover.  Keeping the unit clean when it is not in use means that it will be further protected so when we do need it, the unit is in good condition and ready to go.


The SINGER 4423 sewing machine is marketed as being a heavy duty machine.  Now, many of us have purchased things before that were labeled one thing, such as “ice cold”, “super-powerful”, or “heavy-duty” and those products did not live up to that description, to say the least.  However, SINGER 4423 hit it on the head with this one.  This sewing machine really is heavy-duty and durable.

The sewing machine is manufactured from an internal metal frame with a bedplate of stainless steel.  There are rigid supports, which allows the sewing machine to operate in perfect alignment.  SINGER states that the motor of their machine is also 60% stronger than standard sewing machines. We have not been able to find data to back this up, but this could be why sewing heavier material is easier on this machine.

One thing we appreciate is that while sitting on your table when sewing, the heavy metal components help to keep the sewing machine stable.  You do not have to worry about the unit falling off the table, nor will you have to worry about the material you are working with being fed through the sewing machine at an uncontrolled speed.


At this point, you are probably wondering what the SINGER Heavy Duty 4423 Sewing Machine will run you.  You can easily find this exact same model on for $144.59 with free shipping. The sewing machine comes with a 25-year limited warranty.   This includes 25 years on the head, 2 years on the motor and electronic components, and 90 days on bulbs, belts, and attachments.

This is an excellent starting price for those that are just starting out with sewing.  For all the features that are being offered with this sewing machine, as well as weighing under 15 pounds, this machine is a steal! It also comes with many accessories including Seam Ripper / Lint Brush, Quilting Guide, Needles, Bobbins, Screwdriver, Auxiliary Spool Pin, Spool Pin Felt, Soft-Sided Dust Cover, and a light.  We have found that at this price, the SINGER Heavy Duty 4423 Sewing Machine provides great value for the money spent on it.  This machine is not only built by a reputable company, but it comes with a bevy of features and accessories, along with being built on high-quality.  Add this to the high speed and stable performance and you have yourself a package that is very affordable for the price tag.

Final Thoughts

The SINGER Heavy Duty 4423 Sewing Machine is a great sewing machine for those that are just starting this trade.  We also feel it is great for those that are in the “intermediate” stages of sewing.  Twenty-three stitch choices, along with being so versatile with many kinds of fabrics, make this sewing machine a winner in our book. This sewing machine is definitely worth your time and effort.  The pros far outweigh the cons, making the SINGER Heavy Duty 4423 sewing machine an A+ in our books.
